Patent GB-734409-A (GB)
Title: Non-yellowing triethanolamine salts
IPC: C07C215/12
Filed: 1952-01-07
Abstract: Non-yellowing triethanolamine salts of acids of the types of stearic, oleic, coconut, boric, phosphoric, salicylic, acetic, phthalic and oxalic acids are prepared by a process characterised by using triethanolamine which has been subjected to a pre-treatment with sulphur dioxide or an agent splitting off sulphur dioxide.  Sulphur dioxide may be partially removed from the composition during or after the reaction with the acid by the application of heat. Neutralization of the pre-treated triethanolamine with stearic acid may be effected by merely mixing with prefused stearic acid without evolution of sulphur dioxide, but liberation of part of the latter is observed on further heating.  The amount of acid employed is based on the amount of triethanolamine originally used.  In examples: triethanolamine is treated with sulphur dioxide and fused stearic acid is added (1); in a similar process heating is applied to the mixture and sulphur dioxide escapes (2); oleic acid is mixed with triethanolamine containing sulphur dioxide (3); triethanolamine borate is obtained by heating triethanolamine containing sulphur dioxide with boric acid (4); in a similar process phosphoric acid is employed instead of boric acid (5); and triethanolamine salicylate is prepared by the addition of salicylic acid to triethanolamine containing sulphur dioxide (6).  Salts of acetic, phthalic or oxalic acid may be similarly obtained from triethanolamine which has been pretreated with sulphur dioxide.ALSO:Non-yellowing triethanolamine soaps are prepared by reacting soap-forming fatty acids with triethanolamine which has been pre-treated with sulphur dioxide or an agent capable of splitting off sulphur dioxide.  Sulphur dioxide may be partially removed from the composition during or after the reaction with the acid by the application of heat.  The amount of acid employed is based on the amount of triethanolamine originally used.  In examples: (1) triethanolamine is treated with sulphur dioxide and fused stearic acid is added; (2) in a similar process heat is applied and sulphur dioxide escapes; (3) oleic acid is mixed with triethanolamine containing sulphur dioxide.
Patent GB-842275-A (GB)
Title: Improvements in and relating to glycols
Filed: 1958-01-07
Abstract: The invention comprises bis-tertiary glycols of the general formula: <FORM:0842275/IV(b)/1> wherein R1 represents a primary or secondary alkyl radical (1-5 carbon atoms), an alkenyl radical (2-4 carbon atoms) or a cycloalkyl radical (3-7 carbon atoms), R2 represents a methyl of ethyl radical and R1 & R2 jointly may represent an alkyline radical with 4 or 5 carbon atoms and 4 chain members between the two valencies, and R3 represents an alkyl radical (1-4 carbon atoms) with the proviso that R3 contains at least 2 carbon atoms when R1 contains not more than 2 carbon atoms, and the preparation thereof by condensing an a -hydroxy ketone of the general formula: <FORM:0842275/IV(b)/2> with a mono-metal organic derivative of acetylene, particularly a mono-metal acetylide or an acetylene mono-magnesium halide.  The monometal acetylide is prepared in situ either before the reaction by reacting acetylene with sodium or lithium in liquid ammonia, or during the reaction.  In the latter case the a -ketol is reacted with acetylene in an organic solvent in the presence of finely divided potassium hydroxide.  Examples describe the preparation by the above methods of 3, 4-dimethyl-3, 4-dihydroxy-heptine-(1), 3, 4, 5-trimethyl-3, 4-dihydroxy-heptine-(1), 3-ethyl-4-methyl-3, 4,-dihydroxy-pentine (1) 3-ethyl-4-methyl-3, 4-dihydroxy-hexine (1), 3, 4-diethyl-3, 4-dihydroxyhexine-(1), 3-methyl-4,4-tetramethylene- 3,4-dihydroxy-butine-(1), 3-methyl-4-cyclopropyl 3,4-dihydroxy-pentine-(1), and 3, 4,6-trimethyl-3, 4-dihydroxy-heptine-(1).  Acetylene is reacted with a solution of ethyl magnesium bromide in tetrahydro-furan to produce a suspension of ethinyl magnesium bromide which when reacted with 3-methyl-3-hydroxy-heptanone-(4) gives 3-methyl-4- ethinyl-3, 4, dihydroxy-heptane.  Similarly is prepared 3 methyl-4-ethinyl-3,4-dihydroxy-octane and 3, 4, 6-trimethyl-3,4-dihydroxyheptine (5)- ine-(1).  The a -hydroxy ketones used as starting materials are prepared either by reaction of methyl ketones, R1-CO-CH3 with alkali metal acetylides followed by treatment with mercury oxide & sulphuric acid or by reaction of a -hydroxy-carboxylic acids with methyl-lithium, or by reaction of the cyanohydrins of ketones of the formula R1-CO-R2, the hydroxy group thereof being protected by acylating or reacting with dihydro pyran or a vinyl ether, with a alkyl magnesium halide R3-Mg-Halogen & hydrolysis of the complex.  An ethereal solution of a -methyla -(a 1-ethoxy-ethoxy) - valeronitrile is prepared by treating n-propylmethyl-ketone-cyanohydrin with vinyl ethyl ether, treatment with ethyl magnesium bromide giving 4-methyl-heptanol-(4)-one-(3). Methyl ethyl-ketone cyanohydrin with acetic anhydride and acetyl chloride gives a -methyl-acetoxybutyronitrile, and diethyl ketone cyanohydrin with dihydropyran gives a -ethyl-a -tetra-hydropyranyloxy-butyronitrile.

Title: Method of and apparatus for carrying out physical and chemical processes in which gases, liquids and solids take part at the same time
IPC: B01J8/20
Filed: 1956-01-06
Abstract: <PICT:0796195/III/1> <PICT:0796195/III/2> In a method of carrying out processes in which gases, liquids and solids take part simultaneously, e.g. oxidizing sulphur dioxide to form sulphuric acid using active carbon as a catalyst, a suspension of a solid in a liquid in the form of a pumpable sludge having a solid content of at least 100 kg. per cubic metre is converted into discrete particles and held in the fluidized state above a grid 2 (Fig. 1) by a gas entering at 3 and leaving at 6 after passing through a cyclone separator 7 which returns entrained sludge to the fluidized suspension.  Sludge collecting in the sump 4 is partly withdrawn at 9 and partly recirculated by the pump 5, fresh liquid may be added at 8.  The solid content of the sludge is preferably kept so that the sludge is only just capable of being pumped and the gas load is adjusted to about 7000 cubic metres per hour per square metre of grid area.  The free grid area at the narrowest points of the grid is about 10 per cent of the total grid area.  In oxidation of sulphur dioxide a sludge of active carbon is formed in aqueous sulphuric acid and water is introduced at the point 8.  The sulphuric acid may be separated from the sludge withdrawn from the apparatus by settling, centrifuging or filtration.  In a modified apparatus the sludge is fluidized in a frusto-conical vessel 10 (Fig. 2) having a flared inlet piece 11 which is 1 metre in length for an apparatus through which 2 cubic metres of gas per second is passing.  The length of the piece 11 is varied in accordance with the sixth root of the load. The gas speed in the inlet pipe 3 is between 20 and 40 metres per second.
